OEM 15mm rear sway-bar bushing part number
 

Hello everybody,
i'd like to upgrade the rear sway bar with the new 15mm one but i'm having an hard time finding the correct part number for the bushings.

Usually my reference site for part numbers is parts.subaru.com but i've found there are multiple part numbers in the same diagram so it's quite unclear to me which one is the correct one.

i've already bought what i thought was the right one, P/N 20464CA020 , only to find out that the label on the item is different than the one in the diagram, it say "D 14" at the end of the description, like it was meant for the old 14mm sway...and if i try to mount the bushing on the bar the back remain "open" so i'm quite sure it's not the right one

Can anybody help me?

Thank you very much ;)

20464CA020 is correct, the old bushing was 20464CA010.

I don't know, i don't like the way it fit on the bar...https://uploads.tapatalk-cdn.com/201...2ce1992d39.jpg

I have the STi bush on the front bar, it says 13 while bar is 18.

This the correct fit. When you torque the clamp, the bushing ends will touch each other.

And by the way nice choice to fit the updated rear sway bar.

Thank you, i have a set of Tein Flex Z and i'm trying to address some mid corner understeer...i could have bought a complete (and much stiffer) set of adjustable sways but the risk of "screwing up" everything is high and right now the car is generally fine to drive so i think (hope) i'll be happy with this very subtle mod :)

Usually it is the other way. A set of adjustable sways will offer you more flexibility. There exist vendors that offer sway bars close to OEM specs, but with an additional feature the adjustments. The stock rear sway bar will give you just a single setting. If you don't like it you cannot change it.

Yes you are absolutely right, the lack of adjustability make this a bit of a gamble, but given the fact that i drive the car on both mountain roads and track and given that i'm quite happy about the way it drives (it's very compliant as it is) i really want a subtle mod with the least amount of "side effect"...and i have to say that i usually prefer oem over aftermarket whenever is possible so...we will see :)

You said there are some soft adjustable rear sways on the market...which one do you recommend as an alternative to this one?

They are +1mm thicker (approx. 25% more stiff) and the rear is adjustable.
